Introduction: The development of the necessary infrastructure to enhance the walkability in urban areas has an important role in sustainable urban development and from various aspects of the environment, public health and social justice can improve the quality of life. This study aimed to investigate the pedestrian capability approach for the development of a sustainable city in District 16 of Tehran Municipality as one of the greenest urban areas in Tehran.Material and methods: In this research, the criteria, qualities, characteristics and physical, functional and spatial variables of the man-made environment that affect the amount of walking in the D16 of Tehran Municipality have been studied and collected. Then, using GIS spatial analysis and prioritization of indicators using Analytical Hierarchical Process, the pedestrianization of different parts of the region has been investigated.Results and discussion: Criteria affecting the location of sidewalks and greenways in the D16 in 9 main categories and 30 sub-criteria were collected in a hierarchical structure and their spatial information was collected. The diversity and wide range of indicators evaluated results in a comprehensive analysis of the current situation can be considered as one of the strengths of this study. Each of these indicators was analyzed for the study area and the situation of walking potential in the D16 was studied based on each of the indicators. Using the preference of criteria based on the opinion of experts and the overlap of different layers, finally, the map of the degree of walkability and the map of the degree of the walkability of the road network in the 16th district of Tehran Municipality was obtained. According to the results, the spatial value shows the highest values in Khazaneh, Naziabad and Bagh Azari neighborhoods, respectively. In addition, Bukharai Street, Madaen Street, Rajaei Street and Street next to Besat Park are the axes with the highest amount of pedestrian traffic in the region, respectively.Conclusion: Based on detailed traffic studies, the best places to define sidewalks or urban greenways were identified, and since these axes have a high volume of pedestrian traffic, it is very important to pay attention to the needs of pedestrians in them. The three neighborhoods of Naziabad, Aliabad North and Khazaneh were identified as three suitable areas for the development of pedestrian axes in the region and were introduced to further concentrate the municipality of the region.

Today the issue of waste management is one of the most crucial issues in the field of waste management of large cities. Lack of land for waste disposal and long-term remain of certain types of waste such as glass, plastic and metals, is leading to undesirable environmental effects as well as pollution of soil, water and air. Among the types of waste, household waste accounted a considerable amount of municipal waste and urban studies show that one of the solutions is household waste separated for waste management. Due to the growing volume of waste generated in Tehran and several problems caused the Tehran Municipality has tried to encourage citizens towards waste separation in recent years. This study aimed to investigate the role of training and knowledge in the management of residual household waste. The study area covered Region 8 of Tehran Municipality in 2015. To conduct this research, survey method were applied. The ample of this study was composed of 400 residents of over 15 years old who were living in the region and selected by utilizing quota-random sampling method and the required information was gathered through questionnaires. Analysis was conducted by using spss software. The results also showed that more than half of the respondents have been trained about waste separation. The average level of respondents’ knowledge was reported at high-level. Moreover, analytical results showed that statistically, there was a significant relationship between training and waste separation. Also the amount of training associated with waste separation. According to test correlation people knowledge about waste was associated with waste separation and its correlation was positive and direct. Variables of age, gender, education and income have showed no impact on the separation of waste. In general, the results of this study too empirical support the effect of training on waste separation behavior by citizens and also presented necessity of attention to other social and cultural factors. .In other words, factors training and improving knowledge can not lead to the separation of waste alone and should done a comprehensive study alongside with other factors influencing in the behavior of waste separation.
